I was using ubuntu 18.04 for a while. I have a testcode using boost uart which worked fine. After upgrading the system to 22.04 I can not build it getting errors like error: uart.cpp:(.text+0x3a1): undefined reference to `boost::system::system_category()'. Most of the advice i have found reccomend to add -lboost-system flag, but it always were in my qmake file, nothing changed there.
